ASP signalR简单服务器推送功能

Please see http://go.microsoft.com/fwlink/?LinkId=272764 for more information on using SignalR. Upgrading from 1.x to 2.0 ------------------------- Please see http://go.microsoft.com/fwlink/?LinkId=320578 for more information on how to upgrade your SignalR 1.x application to 2.0. Mapping the Hubs connection ---------------------------- To enable SignalR in your application, create a class called Startup with the following: using Microsoft.Owin; using Owin; using MyWebApplication; namespace MyWebApplication { public class Startup { public void Configuration(IAppBuilder app) { app.MapSignalR(); } } } Getting Started --------------- See http://www.asp.net/signalr/overview/getting-started for more information on how to get started. Why does ~/signalr/hubs return 404 or Why do I get a JavaScript error: 'myhub is undefined'? -------------------------------------------------------------------------------------------- This issue is generally due to a missing or invalid script reference to the auto-generated Hub JavaScript proxy at '~/signalr/hubs'. Please make sure that the Hub route is registered before any other routes in your application. In ASP.NET MVC 4 you can do the following: <script src="~/signalr/hubs"></script> If you're writing an ASP.NET MVC 3 application, make sure that you are using Url.Content for your script references: <script src="@Url.Content("~/signalr/hubs")"></script> If you're writing a regular ASP.NET application use ResolveClientUrl for your script references or register them via the ScriptManager using a app root relative path (starting with a '~/'): <script src='<%: ResolveClientUrl("~/signalr/hubs") %>'></script> If the above still doesn't work, you may have an issue with routing and extensionless URLs. To fix this, ensure you have the latest patches installed for IIS and ASP.NET.
